Just as the title says does anyone use their paddle shifters at all?
Think you misunderstood. Don't think anybody has claimed there is "damage" to your tranny if you use it often to slow down. It is more "wear and tear" to it compare to using the brakes. It is the same idea when you asked about extending the life of the LED headlights by not using DRL.... Some commentators say you'll damage your tranny over time but Toyota told me the ECU wouldn't allow that to happen to use as much as I like.
